Here is who the presidential candidates follow on Twitter

Marco Rubio seems open to following everyone under the sun — Democrats, fellow Republicans, insiders of every type and an odd assortment of outliers who offer advice on matters ranging from body-piercing to playing craps and getting out of debt.

Using Twitter to get a message out is now a must-do for presidential candidates, but looking at the accounts they follow can be instructive, too. Their follow list can reflect not only their personality and interests, but sometimes their strategy. In Rubio's case, it seems to reflect a bit of a problem with spam, as well.

Overall, their choices reflect an interest in people who think like they do. Few Republicans or Democrats want to follow what people on the other side say. And most — Democrats Hillary Rodham Clinton and Bernie Sanders among them — don't follow most or any of their party rivals.

Some candidates rely on hired help to tend their social media affairs, especially those with lots of money and staff, so it's not always clear who's doing the tweeting or the following.

Trump, though, is known to spend the wee hours lobbing rhetorical bombs at Twitter. Cruz, said spokesman Rick Tyler, "does follow Twitter virtually all day long between events." John Kasich has orderly lists of Ohio political and media groups, like a clothes closet organized by style and color. A flood of first-person tweets from others, too, suggests a personal interest in the platform. Jeb Bush, for example, has been tweeting about policy and family since long before his campaign.
